What This Standard Means
What Students Need to Do
- Students examine everyday transformations and decide whether a different material formed. They support the decision with observable evidence, such as lasting changes in color, texture, odor, or hardness.
What Mastery Looks Like
- A student can classify a rusty nail, cooked egg, burned paper, and rotting leaf as cases where new materials form. The student can explain why melting ice or cutting paper does not fit.
Common Misconceptions
- Students may treat every visible change, including cutting or melting, as producing a new material. They may say burned matter disappears or rust is dirt stuck to metal. They may also assume the change must happen quickly or involve heat.
How to Assess It
- Exit ticket: An ice cube melts, an egg cooks, and a nail rusts. Circle the two cases that form different materials, then name one changed characteristic for each.

Ways to Teach It
Place a fresh apple slice beside a browned slice, then have students record changes in color, texture, and odor.
Ask students to write: How do you know cooking an egg makes more than a change in shape?
Sort cards showing melting ice, tearing foil, browning toast, leaf decay, and rusting nails into same material or different material.
Compare photographs of a new bicycle chain and a weathered one, then discuss how oil and dry storage slow rust.
